Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-generic-bitops-v3
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/x86/linux-2.6-generic-bitops-v3:
x86, bitops: select the generic bitmap search functions
x86: include/asm-x86/pgalloc.h/bitops.h: checkpatch cleanups - formatting only
x86: finalize bitops unification
x86, UML: remove x86-specific implementations of find_first_bit
x86: optimize find_first_bit for small bitmaps
x86: switch 64-bit to generic find_first_bit
x86: generic versions of find_first_(zero_)bit, convert i386
bitops: use __fls for fls64 on 64-bit archs
generic: implement __fls on all 64-bit archs
generic: introduce a generic __fls implementation
x86: merge the simple bitops and move them to bitops.h
x86, generic: optimize find_next_(zero_)bit for small constant-size bitmaps
x86, uml: fix uml with generic find_next_bit for x86
x86: change x86 to use generic find_next_bit
uml: Kconfig cleanup
uml: fix build error
